摘要
从波导的等效边界条件出发,结合波导的激发方程组,通过数学推导说明了螺旋波纹波导回旋行波管的模式耦合机制。TE1,1模会在螺旋波纹波导中耦合出TE_2,1模,并且通过计算说明TE_2,1模主要和TE1,1模的空间-1次谐波发生耦合。
Mechanism of mode coupling for Gyro-TWT with helical interaction waveguide is interpreted in this article,which derived from equivalent boundary conditions and exciting equation. TE1,1 will excited TE_2,1 in helical interaction waveguide. Furthermore, TE_2,1 is primarily coupled with-1 harmonic of TE1,1.
